Question

A scientist builds a Mars rover that can travel 4.9 centimeters per second on flat ground. If the rover continues at the same rate, how many centimeters will it travel in 15 1 over 2 seconds?

Answer 1

I’m assuming 15 1 over 2 means 15.5 or 15 1/2, in which case your answer would be 4.9 • 15.5 = 75.95 cm.
